Tecumseh OHH60 replacement suggestions

No, I have not been inside of a tillotson specifically. However this caught my eye in a Cars and Cameras video.


I'm pretty sure that it's plastic.
Here is the video it was in. Its around 2:37.

Hmm, but for a touche, Carsandcameras said multiple times in their recent monster truck videos that the Tillotson 212 is governed at...(drumroll)
Five, thousand, five, hundred, revolutions, per, minute!!!
Soo yeah, I don't think anything'll really come of us arguing any more.

carsandcameras is a fun to watch.. but bad example to follow for the most part..
unfortunately they show some very bad practive while it runs and deliberately hide how miserably it fails in short order...

But alright..
there are two 212 tillotson engines.. the E and the R..
the E is for all I know NOT raceprepped.. to me that means it's governor is still installed and
there are little to no mods installed.
(it comes with a limited 1year warranty for non racing applications)
then there's the 212 R which for all I know is essentially exactly as prepepd as the Tillotson 196R (just not a true 196cc but a 212cc clone)
the governor is removed, cam and springs are installed (hopefully a billet con rod)
and a billet flywheel (the 196R turns ~8k)

NOW.. governed to 5500 rpm is not a thing really..
there are rpm limiting ignition coils
but frankly I doubt it's installed on any of those engines. (people tend to avoid those in general)

Then there's the "makeshift rpm limiter" namely valve flutter, that usually ocurs right around 5000-5500 rpm when NO heavier valve springs are installed and the actual governor is removed

Chances are, that's what CAC meant by saying it's governed at 5500 rpm.

I can't tell for sure, whats certainly NOT the case it that there is an actual governor
(governors !== rpm limiters)
that's governing the engine to 5500 rpms..

it's not impossible that they got hold of a rpm limiting ignition coil and miscalled it "governing"
when they meant "limiting"..
but most likely they talk valve flutter (which again is just limiting not governing)

One would need to open up their engine to know for sure

You see me baffled...
the 196R isn't governed (and revs from what I've read 8k+)
I wonder why one would want the 212 to be rev limited...
I have the funky smell of "no billet con rod" in my nose!

Maybe there are 212 racing classes that require limited engines...*shrugs*

Anyways most importantly:
I wonder what they mean by "modified governor"
since frankly..
the 212's original plastic governor gear can withstand 5k rpm for a while,
but a SHORT while IYAM...

I'd not trust that w/o a 1yr warranty

Also I read on some website that tillotson made their own factory..(not on tillotsons website)
on the engines themselves it says they're ducar engines
ec sells the 196 with the cheapest possible (Ruixing) carb,
not the Tillotson PK carb it usually comes with..

I'm unsure about how much to trust what third party websites
advertise the engine with.. most of all because it's inconsistent.

*shrugs*

I'd love to know if two bought from different sources (say EC and GPS)
are in fact identical

Hmm, it does say the 212R is governed at 5800 RPM, but I wonder if that holds true for the standard Tillie 212.
